When my stepson was either 7 or 8, we would go to the beach to collect shells and sand and make collages and shell animals. I would give him some markers and he would use his imagination on what types of animals he thought it looked like and he would draw on them.
I wanted to teach him about his culture and about my culture, so we did a week each teaching him about the language, food, different events...and he learned alot from that.
We also did summer things such as making windstocks, windchimes, bird feeders, planted seeds and put together a garden together....
